System and Method for Online Sign Up Provider Selection

ABSTRACT

A mobile station selects a provider such as an online sign up (OSU) provider by receiving a pre-association message including OSU selection information from a Wi-Fi network component, such as an access point in communication with the OSU provider, and sending a selection of an OSU provider in accordance with the OSU selection information to the network component. The OSU selection information excludes identification of the OSU network provider or resource, but provides other attributes to the user, such as price or service configuration. The pre-association message may be transmitted as a beacon or using ANQP.

This patent application is a continuation of U.S. Non-Provisionalapplication Ser. No. 13/647,292, filed on October 8, 2012, entitled“System and Method for Online Sign Up Provider Selection,” which claimspriority to U.S. Provisional Application No. 61/669,992, filed on Jul.10, 2012, entitled “System and Method for Online Sign Up ProviderSelection,” both of which are incorporated by reference herein as ifreproduced in its entireties.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The making and using of the presently preferred embodiments arediscussed in detail below. It should be appreciated, however, that thepresent disclosure provides many applicable inventive concepts that canbe embodied in a wide variety of specific contexts. The specificembodiments discussed are merely illustrative and do not limit the scopeof the disclosure.

The present disclosure will be described with respect to preferredembodiments in a specific context, namely a wireless fidelity (Wi-Fi)wireless standard, which may also be known as IEEE 802.11. The conceptsin the disclosure may also apply, however, to other types ofcommunications standards for connecting electronic devices or accessnetworks.

In the current WFA hotspot 2.0 release 2 standard, a user selects theOSU based on the information of the OSU NAI 16 as shown in FIG. 2, butthis information generally is not enough. For example, a user may wantto consider what type of additional services the OSU offers. Anotherexample is that a user may want to access a basic service set (BSS) thatis deployed by the OSU provider, which may provide the lowest price forservice.

As used herein, the OSU provider may be a Wi-Fi provider or a Wi-Fihotspot operator or may be another entity altogether. For example, theOSU service provider may provide network access service itself oroperate a Wi-Fi hotspot. In contrast, if the OSU service provider has noWi-Fi network the OSU service provider may borrow or rent a Wi-Finetwork from a hotspot operator.

As will be more fully explained below, an embodiment method assists withselection of online sign up provider by providing some information viaANQP message or some other message. In an embodiment, the relationshipbetween OSU provider and the BSS is set and sent to the user device fromthe network to user devices for helping select OSU provider to processonline sign up. Embodiments may be implemented in Wi-Fi networks anduser devices, such as a Wi-Fi access point (AP), a Wi-Fi station (STA),and the like.

An embodiment method provides additional information on OSUcharacteristics or OSU provider's characteristics or preference in somepre-association message (e.g., ANQP message or beacon), so that thisinformation can be used by the user or user device to select the OSUprovider to get a subscription. This information may be referred to asOSU selection information. As used herein, the OSU selection informationexcludes the following information pertaining to the OSU provider: theirfriendly name (in multiple human languages) 14, the network accessidentifier (NAI) 16 to be used to authenticate to the Wi-Fi accessnetwork (when configured for WPA2-Enterprise security), the universalresource identifier (URI) of their OSU Server 18, and their Icon(s) 20.In an embodiment, an OSU selection information field 22 is added to theANQP message 24 as shown in FIG. 3. As shown in FIG. 4, the OSUselection information field 22 may indicate a relationship between OSUprovider and BSS.

In an embodiment, the OSU selection information representing a type ofrelationship of OSU provider and BSS is sent via ANQP message 24 or someother element or message (e.g., beacon), more specially, via the“Hotspot Online Sign-Up (OSU) Providers list” (in FIG. 1) and “OSUProvider field” (in FIG. 2) element. The relationship may indicatewhether this BSS (the one that is sending the ANQP element to the userdevice) is the OSU provider's most preferred BSS, or a priority value ofthis BSS for the OSU provider, and so on. An example is shown in FIG. 4of relationship information being included in the OSU selectioninformation field 22 of FIG. 3. Another example is provided in the table26 of FIG. 5 (most preferred BSS), the table 28 of FIG. 6 (own deployedBSS option), and the table 30 of FIG. 7 (priority order option). Therelationship defined in these tables are merely examples and do notlimit other possible definitions of the relationship.

The OSU provider may set the relationship value based on itsrelationship with the BSS. For example, if this BSS is its own deployedBSS, it will set the highest priority for this BSS, or if this BSSoperator gives the OSU provider a good price for a roaming agreement, itwill set the second highest priority for this BSS, and so on. These arejust some examples for how to set the relationship, but do not limitembodiments for other implementations of the relationship.

When the user device receives this information, the user device can showthis information to the user for the user to select a suitable OSUprovider, or the user device can select directly based on theconfiguration policy (e.g., the user sent the configuration policy tothe user device to select the OSU provider of the highest priority BSSwho has the best signaling strength).

In an embodiment, the BSS (operator) sets the relationship value basedon its relationship with the OSU provider. For example, if this OSUprovider is its operator, it will set the highest priority for this OSUprovider, or if this OSU provider gives the BSS (operator) a good pricefor a roaming agreement, it will set the second highest priority forthis OSU provider, and so on. Again, these are just some examples forhow to set the relationship, but do not limit other embodiments withother relationships.

The relationship of OSU provider and BSS is sent via ANQP element orsome other message (e.g., beacon), more specifically, via “HotspotOnline Sign-Up (OSU) Providers list” (in FIG. 1) and “OSU Providerfield” (in FIG. 2) element. The relationship may indicate whether thisBSS (the one that is sending the ANQP element to the user device) is theOSU provider most preferred BSS, or a priority value of this BSS for theOSU provider, and so on. An example is shown in FIG. 4 of relationshipinformation being included in the OSU selection information field 22 ofFIG. 3. Another example is provided in the table 32 of FIG. 8 (mostpreferred OSU provider), the table 34 of FIG. 9 (own deployed BSS), andthe table 36 of FIG. 10 (priority order). A further example is shown inFIG. 1, where the OSU providers listed in the OSU provider list 12element are listed by the order of their priority (e.g., OSU Provider#1, OSU Provider #2, . . . OSU Provider #N). When the user devicereceives this information, the user device can show the information tothe user for the user to select a suitable OSU provider, or the userdevice can select directly based on the configuration policy.

In an embodiment, a Wi-Fi network component (could be an ANQP server, anAP, or AP controller or some other Wi-Fi component) provides additionalinformation about each OSU, which information can be used by the userfor OSU selection. Examples of such information are cost ofsubscription, access to various services, minimum quality of service(QoS) guaranteed, etc. The additional information is sent via ANQPmessage 10 or some other element or message (e.g., beacon), morespecifically, via “Hotspot Online Sign-Up (OSU) Providers list” (inFIG. 1) and “OSU Provider field” (in FIG. 2) element in OSU attributes.FIG. 11 illustrates example OSU provider field 22 format (e.g., the OSUselection information field). FIG. 12 illustrates OSU attributes 38within the OSU provider field 22. The OSU attributes 38 have thefollowing structure: 1 byte the OSU attribute type 40, 1 byte the OSUattribute value 42.

In an embodiment, the information for the OSU selection in the OSUselection information field 22 can be a kind of introduction of the OSUprovider (or service provider), or an advertisement from the OSUprovider. This introduction or advertisement can be a kind of texttransferred from the network to the user device (e.g., via ANQP messageof Hotspot Online Sign-Up (OSU) Providers list format, or some othermessages). For example, it can be as “the best user experience in theworld with a lowest and flexible rate,” or “it is a network from CMCCproviding all over the world coverage and roaming.” When the user devicereceives this information, it can show it to the user and wait for theuser's input, or it can handle it by itself. For example, it can pick upkey word and check the pre-configured key-word in itself. If the keyword matches one of the pre-configured key words, it will handle itaccording to the pre-configured process link to the pre-configured keyword.

FIG. 13 illustrates a OSU attributes type table 44. FIG. 14 illustratesan example table 46 with a value field for available services. Anotherexample is that the available services are listed as a bit map and eachbit indicates a service. When a bit is set to 1, it means that the OSUprovider provides the corresponding service. When the user devicereceives the ANQP message it will display a list of OSU names, andoptionally will display the OSU attributes to allow the user to make aninformation selection.

FIG. 15 illustrates a wireless cellular communications network 48 thatpreferably comprises a plurality of base stations (BS) 50 providingvoice and/or data wireless communication service to a plurality ofmobile stations (MS) 52. The BSs 50, which may also be referred to byother names such as access network (AN), cellular access point (AP), acellular network communications controller, Node-B, etc., preferablydownlink (DL) information to the MSs 52 while also receiving uplink (UL)information from the MSs 52.
